1931- G. E. NERNEY EYEGLASS CQNSTRUCTION Filed Dec. '24, 1926 Q INVENTOR BY W ATTORNEY l at ent ed Aug. 1 931 UNITED STATES PATENT oFFicE GEORGE E. NERNEY, OF ATTLEBORO, MASSACHT TSETTS, ASSIGNOR TO BAY STATE OPTICAL COMPANY, OF ATTLEBORO, MASSACHUSETTS, A CORPORATION OF MAINE EYnGLAss CONSTRUCTION Application filed December 24, 1926. Serial No. 156,855.

This invention relates to eyeglass construction and more particularly to a bridge construction for eyeglass frames.

One of the objects of the invention is to pro- 5 vide an eyeglass frame which is supported upon the wearer in a manner conducive to great comfort. Another object is to provide a bridge construction for eyeglasses capable of a wide range of adjustment to meet various conditions of use. Another object is to provide a construction of the above'nature wherein certain important adjustments may be made without interference with other important adjustments. Another object is to provide a construction of the above nature which is strong and rugged and which, in practical use, is capable of dependably retaining the shape to which it is adjusted to fit the wearer. Another object is to provide a construction of the above nature which is neat in appearance. Other objects will be in part obvious or in part pointed out hereinafter.

The invention accordingly consists in features of construction, combinations of elements, and arrangements of parts as will be exemplified in the structure to be hereinafter described and the scope of the applicatlon of which will be indicated in the following claims.

In the accompanying drawings in which is shown one of the various possible embodiments of this invention,

Figure 1 is a front elevation of an eyeglass frame, and

Figure 2 shows the bridge construction in perspective and in enlarged detail. 7

Similar reference characters refer to similar parts in both views of the drawings.

Referring now to Figure '1 of the drawings in detail, there is shown a pair of eyeglass lenses 10 and 11 which are supported in

rims

12 and 13 respectively. These rims are provided with temple bars 14 and 15 of any der sired construction. The

rims

12 and 13 shown herein are of metal, but it is to be understood that the features of this invention are adapted for use in an eyeglass frame having rims of any desired construction or, if

side portions of the nose.

bars and bridge beingsecured to the lenses by any suitable mounting.

The rims 12 and 18, or the lenses 10 and 11,

are connected by a bridge construction which is adapted to hold the lenses in predetermined position with respect to one another and which is adapted to support the weight of the eyeglasses upon the nose of the wearer. The temple bars 14 and 15, passing over the ears or engaging the skull, prevent the eyeglasses from slipping forwardly out of position. For uniformity of description it may be here noted that the direction forwardly will be employed herein to denote a direction away from the face of the wearer substantially along the line of vision, the term rearwardly being employed to denote the opposite direction; the terms inwardly and outwardly will be employed to denote respectively directionstoward and away from the sides of the nose.

Referring now to Figure 2, the bridge construction is shown indetail. The bridge is preferably made of one piece of metal. A crest portion 16 is shaped to arch or curve over the crest or ridge of the nose and thence 6X tends downwardly on both sides along the Extending rearwardly from the lenses 10 and 11, and in thisv instance connected at their forward ends in I smoothly into the contour of the crest portion 16, meeting the crest portion 16 along the rear edge of its do-wnwardly extending side pore tions. I

The downwardly extending sides of the crest 16 terminate in flattened and preferably widened

end portions

21 and 22 which are adapted to rest against the sides of the nose. These parts or

end portions

21 and 22 are adapted to support against the sides of the nose substantially the entire weight of the eyeglasses, the arch of the crest portion 16 preferably resting lightly against the crest of the nose with very little or no pressure at all. y

The connecting portions 19 and between the shanks 17 and 18 and the sides of the cr st portion 16 join the crest portion at points well above the flat end portions 521 and 22, The construction effected by the downwardly extending sides of the crest portion 16 being split longitudinally, the parts on the front sides of the splits being extended downwardly and terminating in the

flattened portions

21 and 22 and the parts on the roar sides of the splits providing the connecting portions 19 and 20 which are joined to the rear ends of the shank portions 17 and 18. Tie flattened

portions

21 and 22 preferably extend downwardly below the shank portions 17 and 18 and are positioned inside of these portions, and the shank portions 17 and 18 preferably extend rearwardly past the portions 21 and This bridge construction may be adjusted with the greatest convenience to suit any shape of nose and to provide any papillary distance within ordinary ranges. By bend mg or twistin the

portions

21 and 22 these parts may be brought to rest smoothly and comfortably upon the sides of the nose. By manipulation of the shank. portio 17 and 18 with the portions 19 and 20, the pupillary distance and the position of he lenses with r spect to one another may be adjusted throughout a wide range. Moreover, it will be seei'i that these two adjustments are acconu lished substantially entirely independently of one another, tl e making of one adjustment not interfering with the other adjustment. For example, the

parts

21 and 22 may be bent or twisted to fit a very wide nose; thereiuiion, without interfering with the adjustment given the

parts

21 and 22, the position of the lenses with respect to one another may be adjusted by means of the parts 17, 18, 19 and 20 to give a wide pupillary distance or a narrow pupillary distance as the case requires. In addition, the wearer himself, if the eye glasses do not seem to rest comfortably upon his nose, may adjust the

parts

21 and 22 for more comfortable bearing without disturbing the important relation of the lenses one to the other.

In addition to the convenience of adjustment discussed above, it will be seen that this bridge construction connects the lenses in such manner that they are held with great firmness and are not apt to become s 'irung out of proper alinement in ordinary use. The connection between the lenses is directly through the shank portions 17 and 18, the parts 19 and 20 and the crest portion 16, The wide and

flattened portions

21 and 22, supporting the weight of the eyeglasses upon the sides of the nose, make for the greatest comfort, relieving the unpleasant pressure at the crest or ridge of the nose. These end portions or supporting

portions

21 and 22 in addition to being widened and flattened are preferably thinned toward their ends so that they rapidly radiate heat and are thus further conducive to comfort. They are not made so light and thin, however, that they are zip to lose in use the shape to which the are adjusted for the most comfortable fitting.

As many p ssible embodiments may be made of the above invention and as many changes might be made in the embodiment above set forth, it is to be understood that all matter hereinbefore set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.
